Comment on PasswordManagement: which one of these options would you choose?

Option 3: Vaultwarden + Wireguard.
I don’t have to worry about attacks from the internet. And a single wireguard connection on my phone sometimes doesn’t even appear on the battery stats.

could you expand a bit on your edit? so bitwarden extensions need a valid ssl certificate for the domain where the server is hosted? how do you get that for (i assume) a local domain? thank you for your time!

DNS-01 challenge allows for domain ownership verification without open ports and instead looks for a txt record. Using a tool like lego[1] with the respective dns provider’s API automatically creates and deletes the txt record after generating a certificate.
Because the ownership is verified by dns txt entriy, the (sub-)domain doesn’t have to point to a publicly routable host. This allows for using any IP, so I’m using a local ip only available through wireguard or my local network (E.g. bitwarden.example.com points to 192.168.1.123).
The disadvantage is that the provider has to be supported and you have to store an API key for your domain on the server.

that’s genius. i have never even considered that you could use a (sub)domain with a local ip like that to get a certificate from a trusted ca. i ma not sure i understand the neccessity for api access to your dns service. is the txt record for LE different every time you have to pass a challenge? otherwise i imagine you could just set and forget the record.
thank you for the explanation, well appreciated!

Yes it’s awesome. I never even considered that it’s possible to add not publicly routable IP’s to public DNS server, until I recently read a post.
I believe the txt record is different every time.

Not the one who wrote initially, but i have the same setup (mostly).
I went with a self signed certificate. So the server is running with a certificate i have signed with my own certification authority certificate (ca-cert) .
That means I have to install the ca-cert on all devices to get vaultwarden to accept it.
The alternative is a let’s encrypt cerrtificate, which are free, but you need to open port 80 (and another one if I remember correctly) for it to work (at least every 3 months)

If you own a domain name you can uset the DNS-01 challenge instead of hosting a web server to serve the challenge response.
With DNS-01 it will add a TXT record to your DNS zones and check if the record exists to verify that you own the domain.
Depending on which tool you use, they usually support DuckDNS and some other free DDNS providers. If you have your domain on a registrar, chances are that it’s also supported.

Yep that would be a good alternative…I don’t have an official domain for it, so I went the self-signed way
Which enables me to provide tls/https for all my local services. And it was a fun experience to learn
